We are very excited to announce that as part of our September update, we have a preview of aggregations, which allows you to seamlessly store only summarized values in memory without having to load your entire dataset into Power BI, greatly improving the performance of your reports. This month also includes a preview of a PDF file connector, which is the most requested connector on UserVoice; and one of our biggest updates to our advanced query editor in quite a while, M intellisense.

As part of the Microsoft Build event, we are announcing a developer preview of the Data Connector SDK. You can begin to create your own custom data connectors. What are data connectors? Simply put, they are how you connect to data within Power BI. These are extensions on the connectivity/Mashup engine that powers the “Get Data” experience in Power BI and Excel.

Do you want to detect outliers in your data? Want a predictive way to complete missing values in your data, or do you want to perform other advanced analytics scenarios as part of data cleansing? Implementing advanced analytics data cleansing scenarios in Power BI is now easier than ever! Learn more about adding R steps in Power Query as part of the Power BI Desktop July Update.
